What is Pas Yisroel? Pas Yisroel is a bread or pastry product that was baked with the participation of a Jewish person. Are all kosher baked goods Pas Yisroel? No. Unlike many cooked items where the participation of a Jewish person in its cooking is an absolute requirement, with baked items it is only a preference. Therefore, an item certified by a reliable kosher certification should be assumed to be non-Pas Yisroel, unless the packaging bears the Pas Yisroel designation. How are commercially produced products made to be Pas Yisroel? The most reliable way to make a product Pas Yisroel would be for a Jewish person to either place the item into the oven or to turn on the fire. Since this is not feasible in most commercial establishments, most reliable kashrus certifying agencies will use alternate methods to manufacture products as Pas Yisroel.
